CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Provisional Application No. 62/317,784, filed Apr. 4, 2016, the contents of which are entirely incorporated by reference herein.

FIELD

The present disclosure relates generally to firearm safety selector switches. In particular, the subject matter herein generally relates to an adjustable safety selector switch.

BACKGROUND

Firearms often include a safety selector to selectively inhibit operation of the firearm. Safety selectors engage a portion of a firing mechanism, thereby preventing operation of the firing mechanism, thereby preventing operation of the firearm. In some firearm platforms, the safety selector can further be utilized to transition the firearm from a safe position to either a semi-automatic operating mode or a fully automatic operating mode. Customizable safety selectors are available for a number of firearm platforms, including the AR15/M16, that allow users to select the desired length, size, and shape of the safety lever; however, these customizable safety selectors are not adjustable to individual preferences, and as such even with this customization many users have to change grip position to manipulate the controls, specifically between safe, semi-auto and full-auto.

DETAILED DESCRIPTION

It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure.

Several definitions that apply throughout this disclosure will now be presented. The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected.

The present disclosure is directed to an adjustable position safety selector switch for a firearm. The firearm can be any firearm known in the art including, but not limited to, AR15/M16 firearms and air soft replicas. While the present disclosure is shown and described with respect to an AR15/M16 safety selector, it is within the scope of this disclosure to implement the adjustable safety selector with any known firearm platform. The adjustable position safety selector switch allows a user to adjust and/or customize the positions to suit each user based on his/her individual comfort as well as physical characteristics such as hand size, thumb length, or the like. The adjustable position safety selector switch can be adjusted in lever angle, position, length of levers, style of lever, as well as position of an indicator independent of lever angle/position.

The present disclosure is drawn to an adjustable safety selector having a rotatable lock member transitionable between a first position and a second position. In the first position at least a portion of the lock member is configured to inhibit movement of at least a portion of a firing mechanism of a firearm. A first lever member can be coupled with a first end of the lock member and a second lever member coupled with the first end and engageable with an outer surface of the first lever member. The first lever member and the second lever member can be coupled with the first end of the lock member in a plurality of positions. The rotatable lock member can have a longitudinal axis extending through the first end, and the first and second lever members can be independently rotatable about the longitudinal axis into the plurality of positions.

Moreover, while the present disclosure generally refers to an adjustable safety lever having two levers formed on one end or an ambidextrous safety selector having two levers formed on one end a third lever formed on the opposing end, it is within the scope of this disclosure to implement the safety selector having a single lever formed on one end, or a single lever formed on each of the opposing ends.

The following provides a more detailed discussion of the components herein.

FIGS. 1-2 illustrate an example lower receiver and trigger assembly receiving an adjustable safety selector. The lower receiver 10 can receive a trigger assembly 12 and a safety selector 14. The safety selector 14 can be a conventional safety selector or an adjustable safety selector as disclosed herein.

The trigger assembly 12 can include a trigger 16, a hammer 18, and/or a disconnector (not shown). The safety selector 14 can be received in the lower receiver 10 and prevent operation of the trigger assembly by inhibiting movement of the trigger 16, hammer 18, and/or the disconnector. As described below in more detail, the safety selector 14 can be rotatable between a first position and a second position, the first position aligning the trigger assembly 12 with a solid portion disposed on the safety selector 14 inhibiting actuation of the trigger assembly 12 while the second position can align the trigger assembly with a recess portion disposed on the safety selector thereby allowing actuation of the trigger assembly 12.

The safety selector 14 can have a lever 20 to allow a user to rotate the safety selector 14 between the first and second positions. The lever 20 can be sized and shaped to allow actuation by a user's thumb and/or finger during handling of the firearm.

As can be appreciated in FIG. 1, the safety selector 14 is in a first position, also known as a “safe” position. The trigger assembly 12 is abuttingly engaged with the solid portion of the safety selector 14, thereby inhibiting actuation of the trigger assembly 12 and preventing firing of the firearm.

As can be appreciated in FIG. 2, there safety selector 14 is in the second position, also known as a “fire” position. The trigger assembly 12 is aligned with the recess portion of the safety selector, thereby allowing actuation of the trigger assembly 12 and firing of the firearm.

While FIGS. 1 and 2 illustrate a first position “safe” and a second position “fire” it is within the scope of this disclosure for the safety selector 14 to be rotatable between additional positions including, but not limited to, fully automatic mode, semi-automatic mode, and/or burst mode. In some instances, the safety selector 14 can have three positions, a safe position, a semi-automatic position, and a fully automatic position.

Further, while FIGS. 1 and 2 are general drawn to an M16/AR15 lower receiver, trigger assembly, and safety selector, it is within the scope of this disclosure to implement an adjustable safety selector as disclosed herein with any known firearm.

FIGS. 3-5 illustrate a first embodiment of an adjustable safety selector. The adjustable safety selector 100 includes a rotatable lock member 102 transitionable between a first position and a second position. The rotatable lock member 102 can have two opposing ends, a first end 104 and a second end 106 having a longitudinal axis 150 extending along a length of lock member 102 between the first end 104 and the second end 106.

The adjustable safety selector 100 and related components can be formed by machining, die casting, sand casting, milling, injection molding, 3-D printing, or any other manufacturing process known in the art. The adjustable safety selector can be formed from metal, ceramics, plastics, polymers or other material having suitable strength for use with a firearm.

A first lever 108 can be coupled with the first end 104 and a second lever 110 can also be coupled with the first end 104 and abuttingly engage with an outer surface 112 of the first lever 108. The first lever 108 and the second lever 110 can receive a force from a user thus imparting rotation on the rotatable lock member 102 and transitioning the rotatable lock member 102 between the first position and the second position.

The rotatable lock member 102 can have a solid portion 114 configured to inhibit movement of a firing mechanism of a fire arm when in the first position. The solid portion 114 can protrude into the path of one or more movable members of the firing mechanism, such as the trigger and/or hammer, thereby preventing operation of the firing mechanism. The rotatable lock member 102 can have a recess 116 configured to allow free movement of the firing mechanism when in the second position. The recess portion 116 can provide a clear path for the moveable members of the firing mechanism allowing proper operation of the firing mechanism and the firearm. The solid portion 114 and the recess portion 116 can be disposed on opposing surfaces of the rotatable lock member 102. In other instances, the solid portion 114 and the recess portion 116 can be disposed on adjacent sides of the longitudinal axis 150 of the rotatable lock member 102.

The lock member 102 can have additional surfaces to engage the firing mechanism to transition the weapon from a second position, such as a semi-automatic firing mode, to a third position, such as a fully automatic firing mode. The firing mechanism can include a hammer, a trigger, and a disconnector interface. Transition of the lock member 102 to the third position can involve rotation about the longitudinal axis 150 past the second position, such that transition of the lock member 102 from the first position to the third position requires passing second position.

As can be appreciated in FIG. 3 and FIG. 4, the adjustable safety selector can be an ambidextrous safety selector having a lever coupling with each of the first end 104 and the second end 106. The first end 104 can have the first lever 108 and/or the second lever 110 coupled thereto and the second end 106 can have a third lever 118 coupled thereto.

The first lever 108 and the second lever 110 can be molded so as to flushly receive one another, while providing an actuation surface 120 capable of transitioning the rotatable lock member 102. The actuation surfaces 120 of the first lever 108, second lever 110, and third lever 118 can vary in size, shape, or length according to a user's preference.
